What type of replication does MySQL support?
Replication in MySQL features support for one-way, asynchronous replication, in which one server acts as the source, while one or more other servers act as replicas. This is in contrast to the synchronous replication which is a characteristic of NDB Cluster (see Chapter 18, MySQL NDB Cluster 7.3 and NDB Cluster 7.4).

What is SQL replication?
SQL Server replication is a technology for copying and distributing data and database objects from one database to another and then synchronizing between databases to maintain consistency and integrity of the data. In most cases, replication is a process of reproducing the data at the desired targets.

What kind of replication is supported by the My Sequel server?
This is in contrast to the synchronous replication which is a characteristic of NDB Cluster (see MySQL NDB Cluster 8.0). In MySQL 8.0, semisynchronous replication is supported in addition to the built-in asynchronous replication.
What is synchronous replication in MySQL?
With fully synchronous replication, when a source commits a transaction, all replicas have also committed the transaction before the source returns to the session that performed the transaction. Fully synchronous replication means failover from the source to any replica is possible at any time.

What happens when row-based replication is enabled in SQL Server?
If row-based replication is enabled, the replica does not know whether a statement occurred within a stored function on the source, so this condition does not apply.
What is the starting point of evaluation of database-level replication and binary logging?
